#Game This is a mini library intended to be a quick and unobtrusive library for building HTML5 games. It provides the utter basics

Game.tick(function(dt, frameNumber) {});
Game.render(function(ctx) {});
Game.input(function(type, eventObject) {});

From these basic functions you can create your own flavour of a game engine.
